Dave Grohl must be the nicest dude in rock. While the Foo Fighters leader was in Philadelphia over Memorial Day weekend for a wedding, according to the Philadelphia Inquirer, he stayed at the Rittenhouse Hotel in Center City. He went down to the hotel bar on Friday night for a nightcap, for which he left a $1,000 tip. And then on Saturday, he went downstairs for a few more drinks and left another $1,000!

That's pretty sweet, right? Do you know of any notable pop star restaurant tips that we've left out? Leave them in the comments! And shout out to Dave Grohl for being such a generous dude.
